My use of the adapters is not a traditional one. I am a collector of lanterns and flashlights. Batteries are part of that equation and a risk. These adapters allow use of AA cells in display pieces rather than the more costly D cells, and if the batteries leak the leak is contained causing no damage to the flashlight. They are worth their cost in peace of mind.

This is my second purchase of the Eneloop AA to D battery adapter. A couple of years ago I bought 4 similar adapters. I say similar because this recent purchase is of Eneloop's new model. For those of you who are unaware of how this works, a standard AA battery fits into the Eneloop casing and can be used as a D size battery. Now it's not like D batteries are hard to find, it's just that I find that I store more AA batteries on hand than I do D batteries. I have a Coleman LED lantern and a Military style angle head flashlight. Both units require D batteries. These Eneloop adapters allow me to utilize AA batteries in these lights and they work perfectly. Now I expect AA batteries will not last as long as D batteries, so I prefer using AA rechargeables; Eneloop makes pretty good rechargeable AAs with a higher mAh than regular AA rechargeables (meaning they will last longer than regular AAs). It is also faster to recharge AA batteries than D size batteries, and you don't have to own two different chargers. So overall, I feel that these adapters are more efficient in the long run. Regarding the new model adapters, they are a significant improvement over their predecessors. The older models allowed you to side in a AA; utilizing the negative terminal of the AA battery. The new version actually has a screw lid which you remove and insert the AA battery and screw back on. The AA is fully enclosed in the new model and the negative terminal has a much wider terminal base (similar to a D battery). Both models have worked fine for me. I am yet to see how durable the new models are, but I believe Eneloop is a quality brand and I feel that these adapters will last a lifetime.Read full review

Gives a large area for negative spring to have good electrical and mechanical contact. Also completely contains the AA: no batteries slipping loose and falling out as with old style open back adapter.

Multiple weaker AAs transform into an efficient C rather than equaling the later with a mere AA for nowadays devices; thus using this sort of adapter is genuinely unnecessary. b n.
